Abstract

The utility model relates to a dual-function terrazzo grinding machine which is on one machine body, is driven by one electrical machine and controlled by one switch of an ordinary electrical machine to respectively flat grind the earth surface or side grind the ground base with the protection for wall corners. The rotation of each grinding disc is controlled by the reversing switch of the electrical machine through the action of an overrunning clutch in the dual-function terrazzo grinding machine at the time of working. A flat grinding head is started to run and a side grinding head is resting when the electrical machine rotates clockwise. The side grinding head is started to run and the flat grinding flat grinding head is resting when the electrical machine rotates anticlockwise. The machine body is additionally provided with a side grinding mechanism, which can enlarge the range of application of the terrazzo machine, can replace the portable grindstone tool, can improve the labour condition of workers and can improve the work efficiency of grinding and the decorative quality. The utility model can be widely used for the engineering construction of the capital construction.

Description

Dual-function terrazzo grinding machine

The utility model relates to a kind of special-purpose machinery that grinds ground and foundation side ground smooth of infrastructure project construction.

Existing terrazzo machine only is confined to the grinding on parallel ground, to then idle victory of grinding work perpendicular to the side on ground.In construction work, when design wall side grinding stone, purchase portable grindstone tool usually in addition and use.Because the deadweight of portable grindstone tool is more stupid, the power that should mention during use is exerted pressure to grinding place again, so the workman is difficult to lasting drawings.Therefore deduction and exemption are decorated in the capital construction design, or substitute with prefabrications such as ceramic tiles, so both fettered the optional of decorative pattern kind, increase construction costs again, so the flat stone mill on simple parallel ground does not satisfy the needs of the building cosmetic treatment in flourishing city day by day far away.

Innovation of the present utility model development provides a kind of difunctional optimum facility, can plain grinding, again can side grinding, realize a tractor serves several purposes: solved the engineering machinery equipment of unit in charge of construction's desire meaning, beautified implementation condition thereby enlarge building.

In conjunction with the embodiments the utility model is elaborated:

Realize that the difunctional grinding scheme of a tractor serves several purposes is:,, control the running of each mill by the effect of freewheel clutch by motor (3), three-phase two-direction switch (1).When motor is clockwise, start side grinding head (13) running, side grinding head (14) is static not to be changeed.During the motor counter-rotating, start side grinding head (14) running, plain grinding head (13) is in static state.

Casing (8) geometry is designed through improving, the fixing vee-pulley (43) of going up plain grinding head (13) the axis upper end of vee-pulley driving by motor (3) of casing (8) inner chamber, (43) lower bevel embedding profile of tooth body or friction material filling member (57) are in transmission trailing wheel (35) right angle intersection, the vertical axis electronic-controlled power steering is the rotation that parallels to the axis, (32) in freewheel clutch, (33), (34), (40), (41), (42) characteristic, the diaxon sound attitude requirement of control plain grinding head (13) and side grinding head (14), promptly realize one when changeing, then another mechanical action that stops (referring to accompanying drawing 3 and accompanying drawing 5).

In operation, obtain the equilibrant force of the grinding face of mill for making bistrique, (21) embedding steel ball shape key (22) on the ball head of (51) embedding waist shape key (52) and side grinding head (14) on the ball head to plain grinding head (13), can active tuning transferring power, when grinding tool is consuming or people when holding up the differential seat angle that operation produces, can remove the debugging of proofreading and correct fuselage from, and ad hoc Automatic Levelling simplification device (referring to accompanying drawing 6 and accompanying drawing 7).

Operation instruction of the present utility model is as follows:

When need with plain grinding heads (13) when work, with the dial plate of motor switch (1) at " polishing " word upwards, the plain grinding head promptly rotated to execute and polished ground this moment.When need with side grinding head (14) when work, with the dial plate of motor switch (1) at " side grinding " word upwards, this moment, the side grinding head promptly rotated, and executed mill foundation base side (referring to accompanying drawing 2 and 3).

Execute polishing when ground, should with regulating handle (7) along in the fuselage to displacement, make the ramuscule wheel (12) be liftoff to suspend, make fuselage from the abundant land of gravity on each sand post of plain grinding dish, increase grinding pressure, improve grinding efficiency (referring to attached Fig. 1 and 2).

When executing mill foundation base side, then regulating handle (7) should be shifted along fuselage is export-oriented, and slightly exert pressure; locking screw (5) fastening it; ramuscule wheel (12) lands plain grinding head (13) top-hung is liftoff, and except that protection plain grinding sand post, it is light to obtain the operation go-cart simultaneously.When go-cart, should be with the travelling wheel that places the side grinding women's head-ornaments to (10) the wall side that reclines, the oriention benchmark that travels (referring to accompanying drawing 2).

In same indoor mill ground level and mill basic side operation,, attrition (referring to accompanying drawing 3 and 4) can be carried out in that room, back like this with better about branch to two supporting results of use of stone mill.
